Fix for the repro from the previous PR. A `Capture x -> y` effect should downgrade to `ImmutableCapture` when the source value is maybe-frozen. MaybeFrozen represents the union of a frozen value with a non-frozen value. --- [//]: # (BEGIN SAPLING FOOTER) Stack created with [Sapling](https://sapling-scm.com). Best reviewed with [ReviewStack](https://reviewstack.dev/facebook/react/pull/35140). * __->__ #35140 * #35139
